The miniature die confocal optical head for the confocal imaging device null confocal imaging device and the especially endoscope which use the integral scan type miniature

摘要

As for also this invention for focus imaging device (for especially endoscope) also miniature type regarding the focus optical head (4) being something, this head the light beam (13) the point light source which occurs (2b) with, in one end of the optical head is arranged (outside part), the inspection body (15) observation range of vision under the surface (14) the excited point which is located inside (19) the ball lens in order to make the aforementioned light beam converge (12) with (opening factor of this lens and size of the point light source also assembly ones have reached the point where focus characteristic is guaranteed)In order, the excited point (19) to scan the aforementioned observation range of vision, scan expedient in order it turns to displace (10, 21 and 22) with it has the point light source. The device of this invention has very satisfactory optical quality and of the homogeneous (ball lens with spherical symmetry over full range of vision optical aberration the fixed is over full range of vision) also focus picture in real time (approximately 10 pictures/second) being something which makes you obtain possible, achieves this with the miniature type head.
